On 26 August 2022, Victoria agreed to raise the minimum energy efficiency standards for new homes from 6 to 7 stars, in line with the changes to the National Construction Code 2022.
Energy-efficient homes are more comfortable, cost less to heat and cool, and contribute to reducing greenhouse gas emissions.
These changes introduced a Whole of Home energy use budget, covering fixed appliances like heating, cooling, hot water, and lighting, making homes more cost-effective, comfortable, and resilient to extreme weather.
Updated standards for new homes are mandatory in Victoria starting 1 May 2024.
Victoria will also remove barriers to installing efficient electric hot water systems, encouraging households to benefit from solar panels and supporting those opting for all-electric homes.

The 7 Star Homes initiative collaborates with businesses and individuals throughout the building and construction supply chain to enhance the skills and capacity needed for delivering energy-efficient homes.
Sustainability Victoria is offering rebates to registered builders and land developers for designing and constructing homes with a 7-star NatHERS rating. They are also providing online training tools to help builders, designers, and assessors transition from 6-star to 7-star homes.
Rebates are available to help lower the initial cost of installing solar panels (PV), solar hot water systems, and solar batteries. Additional incentives, such as interest-free loans for solar panels (PV), are also offered for both existing homes and homes currently under construction.
Households with solar installations can save an average of $1,073 per year on electricity bills by producing and using their own energy.
Homes that install both solar panels and solar hot water systems or an energy-efficient heat pump can save up to $1,473 annually on electricity costs.
